Description
Technical Field
[0001] The invention relates to the technical field of dehumidifiers, in particular to a split-type industrial dehumidifier. Background Art
[0002] Dehumidifier is also called dehumidifier, dryer, dehumidifier. Usually, a conventional dehumidifier is composed of a compressor, a heat exchanger, a fan, a water container, a casing and a controller. The fan draws humid air into the machine and passes through the heat exchanger. At this time, the water molecules in the air condense into water droplets. The treated dry air is discharged out of the machine. This cycle keeps the indoor humidity at an appropriate relative humidity.
[0003] For refrigerated dehumidifiers, at relatively low temperatures (generally below 10 degrees Celsius), the heat exchange system of the dehumidifier will inevitably frost, and after a certain degree of frost, it must be shut down for defrosting to avoid affecting the dehumidification effect. After the dehumidifier is shut down, if the relative ambient temperature is low, its defrosting time will be relatively long, resulting in a long period of inability to work, and during the frosting process, the dehumidification efficiency of the dehumidifier is always in a declining state. On the other hand, when the existing dehumidifier is in a high temperature state such as summer, the heat of its heat exchange system is directly discharged indoors, which will further increase the indoor ambient temperature. To this end, we propose a split industrial dehumidifier. Summary of the invention
[0004] The object of the present invention is to provide a split-type industrial dehumidifier to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a split-type industrial dehumidifier, including an evaporator and a heater, the evaporator is composed of a pipeline connected to a compressor and a fin plate arranged on the pipeline, and a frost-clearing wire in the shape of a variable diameter spiral is provided between adjacent fin plates, the frost-clearing wire is evenly distributed on the end surface of the fin plate, and one or two opposite frost-clearing wires are provided in the same axial direction of two adjacent fin plates. A plurality of adjusting rods are also provided in the dehumidifier body, and the adjusting rods are used to adjust at least one end of the frost-clearing wire to move it axially. When one end of the frost-clearing wire moves axially, the axial compression causes the radial expansion, and the frost on the surface of the fin plate is scraped when the frost-clearing wire is in contact with the fin plate.
[0006] Preferably, two groups of frost clearing wires are provided between the same axial direction of adjacent fin plates, and the large diameter ends of the two groups of frost clearing wires are in contact with the adjacent fin plates. A movable ring is threadedly connected to the adjusting rod, and the small diameter ends of the two groups of frost clearing wires are fixed to the movable ring and move therewith.
[0007] Preferably, the movable ring is coaxially corresponding to the pipe opening on the fin plate.
[0008] Preferably, the outermost circle of the large diameter end of the frost clearing wire is of equal diameter.
[0009] Preferably, the outermost circle of the large-diameter end of the frost-clearing wire is polygonal, and the outermost circles of the frost-clearing wires corresponding to the same fin plate fit together in a compressed state.
[0010] Preferably, the cross section of the frost clearing wire is trapezoidal, and the cross section line of one side surface along the radial outward side surface or the two side surfaces along the radial direction is bucket-shaped.
[0011] Preferably, a side of the frost clearing wire that is attached to the fin plate is provided with an inner concave surface.
[0012] Preferably, a heating wire is also provided in the dehumidifier body at the air outlet end.
[0013] Preferably, the heat outlet end of the compressor in the dehumidifier body is provided with an openable and closable branch, one end of which is connected to the heater and the other end leads to the outdoor heat dissipation end.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] The present invention arranges defrost wires between the fin plates, and the axial movement of the defrost wires changes the radial position, thereby scraping the frost on the surface of the fin plates, avoiding the need to stop the machine for defrosting due to frost. Not only does it not need to stop the machine, but also because there is no frost occupying the channel between the fin plates, the efficiency of the evaporator will not be affected.
[0016] The bucket shape and the inner concave surface at the bottom of the frost clearing wire of the present invention can effectively prevent frost blocks from blocking and hardened frost from causing a dead angle problem in the frost clearing wire. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0029] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 The present invention provides a technical solution: a split-type industrial dehumidifier, comprising a filter 10, an evaporator 1, a condenser (not shown), a heater 8 and a fan (not shown) arranged in sequence from the air inlet to the air outlet in the body of the dehumidifier, Figure 1 The figure shown in is only for illustration, and the wind direction is not limited to horizontal. Through the cooperation of the air duct and the fan, the wind can be discharged and inlet in various directions. The filter 10 is used to block floating objects in the air at the air inlet. The evaporator 1 and the heater 8 are respectively the cold end and the hot end (low-pressure area and high-pressure area) connected to the compressor. The evaporator 1 absorbs heat by evaporation of liquid refrigerant in a low-pressure environment, thereby reducing the air temperature, condensing the water vapor in the air into water droplets, and discharged into the collection area on the condenser. After gasification, the refrigerant enters the heater 8 through the compressor to release heat, thereby heating the dehumidified air;
[0030] Because the evaporator 1 absorbs heat, frost will form on the evaporator 1, and on the pipe 2 and the fin plate 3. After a long period of frost, the area between two adjacent fin plates 3 will be blocked by frost, resulting in a reduction in air flow and reduced efficiency. Therefore, a defrost wire 4 is provided between adjacent fin plates 3 to clean the frost. The defrost wire 4 is in the shape of a variable diameter spiral, such as Figure 4 and Figure 5As shown, when the variable diameter spiral frost-removing wire 4 is axially extruded, each circle of the whole will expand radially outward. With the extrusion, each circle first fits the surface of the fin plate 3 and continues to expand radially outward, thereby scraping the frost on the surface of the fin plate 3. On the surface of a single fin plate 3, the frost-removing wire 4 is evenly distributed so as to clean the side surface of the entire fin plate 3 as much as possible.
[0031] As one of the implementation modes, a defrost wire 4 is axially arranged on one side of the adjacent fin plates 3, and the two ends of the defrost wire 4 are respectively correspondingly fitted on the opposite sides of the two adjacent fin plates 3, and the fin plates 3 are slidably arranged on the pipe 2, and the adjusting rod 5 is threadedly connected with the fin plates 3, so that the end movement of the defrost wire 4 can be changed by adjusting the movement of the fin plates 3, thereby axially extruding, and the final state is that the two adjacent fin plates 3 are nearly fitted, and the defrost wire 4 is located in a compressed state between the two, and the surfaces of the two fin plates 3 are cleaned. Because the two adjacent fin plates 3 need to move relative to each other under this embodiment, the threaded connection pitch between the adjusting rod 5 and each fin plate 3 is different, or the fin plates 3 are divided into two groups, and the two groups are alternately spaced, one of which is fixed on the pipe 2, and the other slides and moves with the adjusting rod 5 to compress the defrost wire 4;
[0032] As another embodiment, a defrost wire 4 is axially arranged on one side of the adjacent fin plates 3. The defrost wire 4 is in the shape of an hourglass with large diameters at both ends and a small diameter in the middle. The adjusting rod 5 is connected to the middle part of the defrost wire 4. The connection method can be a fixed connection or a threaded connection. One moves directly and the other is driven by rotation. The two large-diameter ends of the defrost wire 4 fit the opposite sides of the two adjacent fin plates 3. The middle of the defrost wire 4 is driven to move back and forth by the adjusting rod 5, thereby compressing the two ends to fit the fin plates 3 for cleaning.
[0033] As another embodiment, two opposite frost-clearing wires 4 are axially arranged on one side of adjacent fin plates 3, such as Figure 8 As shown, it is similar to the previous embodiment, except that one frost clearing wire 4 is provided as two;
[0034] In summary, the frost clearing wire 4 can be set as long as it can move axially under the action of the adjusting rod 5 and can clean the opposite sides of the two adjacent fin plates 3 when moving. For example, a single spindle-shaped frost clearing wire 4 can also achieve the above effect. However, it is not convenient to set and move the large diameter section, and it is also easy to cause the problem of bulging of the middle circle layer, so it is not described.
[0035] The adjusting rod 5 moves or rotates under the driving of the driving mechanism to change the state of the frost clearing wire 4, and the driving mechanism corresponding to the adjusting rod 5 is driven at a fixed time so as to clean the frost when no large frost is formed.
[0036] See also Figure 3 and Figure 8 Two groups of defrost wires 4 are provided between adjacent fin plates 3 in the same axial direction as a preferred setting. Compared with the setting of a single defrost wire 4, the movement of the fin plate 3 will weaken the heat transfer between the pipe 2 and the fin plate 3, and at the same time, due to long-term sliding, there will even be a gap fit state between the two, further affecting the heat transfer. On the other hand, because the fin plate 3 is large, there will be more resistance to movement;
[0037] The setting of the movable ring 6 is, firstly, to facilitate the overall connection of one end of the defrost wire 4, and secondly, it is sleeved on the pipe 2, corresponding to the position of the pipe 2 on the fin plate 3, and can clean the surface of the pipe 2 when sliding. Another function is to better distribute the defrost wire 4, and to be coaxial with the pipe 2, thereby avoiding the influence of the pipe 2 on the distribution of the defrost wire 4 on the surface of the fin plate 3;
[0038] The two separate frost clearing wires 4 are more convenient to connect and install with the moving ring 6 .
[0039] See also Figure 4 Because a single defrost wire 4 is spiral, the maximum defrost range when it is compressed and expanded radially is determined by the outermost circle. Therefore, the outermost circle is in a regular state, which is more conducive to setting a suitable diameter and setting a smaller defrost wire 4 in the uncovered area to cover the entire fin plate 3, thereby achieving the purpose of increasing the coverage rate and more comprehensive defrosting;
[0040] like Figure 3 and Figure 7 As shown, the outermost circle of a single frost-clearing wire 4 is polygonal, and adjacent frost-clearing wires 4 can fit together in the final state, which can avoid dead angles between each other compared to the circular shape, and is preferably set to Figure 7 The pentagonal structure shown in the figure has straight edges between adjacent defrost wires 4, and other positions are arranged at edges parallel to the edges of the fin plate 3 to achieve overall coverage. There are fewer uncovered positions at the initial end, and the surroundings of the pipe 2 are fully covered. Figure 3 The regular hexagon has dead corners (black areas), the pentagon is more comprehensive, and the outer circle expansion force of the regular polygon structure is more stable and balanced.
[0041] See also Fig. 9 The left and right sides of the cross section of the frost clearing wire 4 or the side radially outward are shaped like a bulldozer bucket. This method makes the bottom of the frost clearing action surface of the frost clearing wire 4 sharp, so that when the frost clearing wire 4 expands outward, it can better shovel the frost. The arc-shaped curved surface structure forms the effect of a plow bucket, which can guide the shoveled frost blocks and eventually turn them over, so as to avoid the shoveled frost blocks from gathering and accumulating, making it difficult for the frost clearing wire 4 to expand.
[0042] The reason why both sides are configured as buckets is that when the frost clearing wire 4 is in the reset state, it can also play the role of secondary scraping;
[0043] For further information, see Fig.10 When the bottom of the frost-clearing wire 4 is in a flat state, when it expands radially, if it encounters relatively hardened frost with a relatively smooth surface, the frost-clearing wire 4 will Fig.10 The frost is lifted up, and one side of the action surface will pass over the frost that is partially attached to the edge of the hardened frost ice. After passing over, the bottom of the frost clearing wire 4 away from the working surface on the side (radial inner side in the expanded state) will compress the frost, and the compressed frost will form a frozen state, making it difficult to be shoveled up by the frost clearing wire 4, and then continue to expand, and the machine can only be stopped for defrosting. Therefore, in order to avoid the influence of the hardened frost ice, a concave inner concave surface 7 is provided at the bottom of the frost clearing wire 4 to accommodate the hardened frost ice, so that the bottom edge of the working surface can contact and shovel the frost close to the periphery of the hardened frost ice, and no dead angle will be generated to cause the hardened frost ice to expand;
[0044] In order to avoid the formation of hardened frost, the cleaning cycle of the frost removal wire 4 should not be too long. At the beginning of frosting, the frost on the surface of the fin plate 3 is easy to shovel, but after it forms a certain thickness, it is difficult to shovel and becomes frozen.
[0045] See also Figure 1 Because the temperature generated by the heat dissipation end of the dehumidifier itself is not high when the ambient temperature is low, it is difficult to make the dehumidified air relatively high. Therefore, a heating wire 9 is arranged inside the air outlet to further heat the air through the heating wire 9, thereby outputting the dehumidified air with a higher temperature;
[0046] When the ambient temperature is high, if the heat outlet of the dehumidifier is still directly indoors, the ambient temperature will further increase. Therefore, in order to avoid this situation, the heat outlet is discharged to the outside in a similar way to the outdoor unit of an air conditioner.
